H Oneof theo j therpr-esent invention isto provide a mechanismfor-controllingthe operation of a machine the use of which will preventor minimizefatigue tof'the; operator. I 1 One feature'of theinventioma'ccordingly, resides in a mechanism for controlling theoperation ofa' machine having-afoottreadle secured to the lower portioncf the-base of the machine, a bracket secured'to the machine base,-asecond foot treadlepivoted toisaid bracket and located above saidfirst-mentioned foot treadle, Y and connections between the 'treadlesincluding a lever actuated only byzthe upper'treadle wherebyanoperatormay control the operation -"of the machine from a a pluralityvof positions, said-treadles-being so arranged'that the use of one ofthe treadles is not interfered with by. thewther treadle. Preferably andas illustrated the. machine is provided with the vusualfoot-operated'treadle treadles located above the usual .treadlesof themachine in such position that the 3-,

erator whenseated in 'front ofthe machine, for example, on a high stool,may use the auxiliary treadle machine. The illustrated treadle mechanism'may be applied 'tomachines of the type disclosed in the above-mentionedLetters Patent, or,

to other machines wherein the operation of the machine is controlledthrough foot-opercontrolling the operation of the =fasteninginsertingmechanism of the machine. .machine is also provided with the-usualfootoperated treadle 1.41 which is connected to, the

a The mechanism for operating-'thefmachine while :the operator is inyasitting ;position will now-be described. aAtreadlc 221isplaced in such aposition that the operator while .sit-

rest his foot on I the 'treadle .and; operate i-itfto chair is arrangedrelativelyfto the front of themaehineandheightwise inthemost contheparticular operator of the machine.

v vThe seat of .theillustrated chair is about of a vertical line throughthe center of the horn tip of the machine. These dimensions, however,will naturally depend both on the dimensions of the machine and the sizeof the 5 operator. The chair has a back rest 26 arranged in the mostsuitable position to support the back of the operator. The height of thechair may be varied in any suitable manner in accordance with the heightof the operator. 1

The treadle 22 is pivoted at 28 to a bracket 30 which is fixed to one oftwo vertical parallel bars or arms 32, 32 connected together at theirupper ends bya bolt or cross bar 34 and fixed at their lower ends to thebase 10 at the rear ofthe column 12. V Stay bars 36,- 36 are fixed'attheir lower ends to the base 10 by 'meansof a pin 37. which also forms afulcrum for the treadle lever 14. The upper ends of the stay bars 36 areconnected to the bars 82, 32 thus holding the bars 32 rigidlyin'position. "A block 38'is adjustably fixed to the forward portion ofthe treadle 22. The heel of they operator rest-s against the block 38and the position of the block maybe varied'in accordance with therequirements of the particular operator. As shown in Fig. 3, the for- I.ward end of the treadle 22 does not extend forwardly 1 of the base'12Qand accordingly does not interfere inany (way with the operationofthe machine the treadle 14.

The rear end of the treadle 22 is pulled down about its pivot by aspring 40'connec ed at one end to an'arm 41 extending rear- Wardly fromthe treadle 22 and at the other end to one of the vertical bars 32. Themovement of the treadle 22undcr the influence of the spring is limitedby a stop screw 44 fixed in the bracket 30. A lever 46 is pivoted on thebolt 84 and one arm of this lever extends under but not quite in contactwith the treadle 22; A plate 48 fixed on the treadle 22 is engaged bytheforward end of the lever 46 when the treadle is depressed, the plateacting to prevent wear on the bottom surface of the treadle. The otherend of the lever 46 is forked, as shown in dotted lines in Fig. 2, andengaged beneath a block 50 which is adjust'ab'ly fixed on the rod 16 bya set screw 51. A rest 52' for the'left foot of the operator is arrangedat the leftsha nd side of the machine and this rest'is fixed bya,bracket 54 to one of'the stays 36 and by abracket 56 to the base 10' I:i "The treadle mechanism just described was developed particularly foruse when'the machine isemployed forslugging looseheels, though'obviouslyit can beused'under other conditions.

The operatormay work alternately in a sitting or standing position andthis change is readily made by merely moving the chair toward oraway'f-rom the machine.
